Abstract

Fetal trisomy 18 is the second most common multiple malformation syndrome. We present four cases of trisomy 18 with multiple sonographic abnormalities at 13 and 14 weeks of gestation. These cases demonstrated that fetal hand deformities can be a tell-tale sign of trisomy 18 with or without increased nuchal translucency at this gestation.
